Using the concepts of rocks, we got that the expansion of deeply buried rocks after they are exposed by erosion causes the formation of Fractures.
Fractures along which the rock has slipped relative to the other side are called faults, whereas fractures that are the simple cracks where the rock has pulled apart by the small amount are joints. Any fracture or system of fractures along which the Earth moves is known as a fault. Faults allow the blocks to move relative to each other which actually results to an earthquake.
When deeply buried rocks are uncovered by the erosion, the removal of weight allows them to relax and expand. Produces fractures and it increases in porosity. This stress-relaxation process actually reduces the strength of rocks, opening up passageways/storage places for the water to attack and further weaken the rocks.
Hence, the expansion of deeply buried rocks after they are exposed by erosion causes the formation of Fractures which reduce the strength of the rock.

Arab and berber traders helped facilitate the gold-salt trade in africa. What part of africa had an abundant supply of salt that was traded for gold?.
Gold and Salt were the two most important trade items. Gold came from the forest regions and rivers (they were very plentiful). West Africa lacked salt, but the Sahara had deposits of salt.
The gold and salt trade across the Sahara has been going on for centuries. Gold from Timbuktu, a city in the modern West African nation of Mali, and other West African countries was traded north to the Mediterranean in exchange for luxury goods and, ultimately, desert salt. , Senegal, South Africa, Sudan and Tanzania are the top ten salt-producing countries in sub-Saharan Africa.
Salt produced in these countries has a wide range of uses and has the potential to have the greatest impact on iodized salt coverage in the region. Not surprisingly, the gold and salt trade between the Ghana Empire and the Arabian desert traders flourished.

which statement about radon is not correct?
This claim regarding radon is untrue. Modern home construction lowers the risk of radon gas buildup.
The uranium decay cycle produces the radioactive gas radon, which is a naturally occurring substance. It is an inert gas that has no flavor, color, or odor.
When uranium, thorium, or radium, which are radioactive metals, decay in rocks, soil, or groundwater, radon, a radioactive gas, is naturally produced. People can be exposed to radon mainly via inhaling radon in air that enters buildings and homes through cracks and crevices.
Lung cancer risk rises with radon exposure over time. The second most common cause of lung cancer in the US is radon.

Which of the following situations would result in a relatively higher regional elevation?
A. Cool, dense oceanic-crust lithosphere far away from the mid-ocean ridge
B. Dense lithosphere replaced by less dense asthensophere
C. Subduction of oceanic crust lithosphere in a trench system
D. A region with thin lithosphere (such as the mid-ocean ridge)
A location with a thinner lithosphere will have a comparatively higher regional elevation as the thick lithosphere is replaced by the less dense asthenosphere.
When the lithosphere in a certain area is heated, it expands and becomes less dense, elevating the area as a result. Because less thick asthenosphere is replacing more dense lithosphere in this instance, thinner lithosphere likewise produces greater heights.
Regional heights are largely governed by crustal thickness, although they can also be impacted by the upper mantle's material composition, temperature, and density.
Different geologic histories of different places are reflected in disparities in crustal thickness. The highest point on Earth is Mount Everest's summit, which is located in both China and Nepal.

which of the following are ways in which a stream will typically respond to increases in discharge?
The width, depth, and velocity of the stream often rise along with the discharge. Position in the stream channel, abnormalities in the stream channel brought on by resistive rock, and stream gradient all affect a stream's velocity. Water near channel edges is slowed by friction.
Flooding happens when a river's discharge exceeds the volume of its channel, causing the river to overflow into the floodplain, the region next to the channel. Several things can cause the discharge to increase. The most frequent reason for floods is heavy rain. Long periods of rain cause the soil to get saturated and lose its ability to retain water, increasing surface drainage. Floods and higher discharge levels will result from rainwater entering the river much more quickly than it would if the land weren't saturated.

Divergent plate boundaries are characteristic of sea-floor spreading centers.
What is Divergent plate?In plate tectonics, a diverging plate boundary is a linear feature that exists between two tectonic plates moving away from each other. Divergent boundaries within continents initially create rifts and eventually rift valleys. The most active divergent plate boundaries occur between oceanic plates and exist as mid-ocean ridges.Current research suggests that complex convection currents within the Earth's mantle allow material to rise to the bottom of the lithosphere beneath each plate boundary where it diverges. This brings a tremendous amount of heat and pressure loss to the region, melting rock from the asthenosphere below the rift region and forming large flood basalts or lava flows. Each eruption occurs only part of the plate boundary at a time, but when it does, it fills the aperture gap as the two opposing plates move apart.To learn more about Divergent plate from the given link :

A geological event is a dynamic, diverse, and temporally distributed occurrence in Earth history that alters the Earth system and results in the production of geological strata. a clearly defined occurrence in which one or more geological processes alter geological entities. Major geological occurrences are caused by plate tectonics when portions of the Earth's crust clash, drift apart, or glide past one another. The kind of plate boundary affects the events' nature. In addition to their rapid start, geologic dangers frequently have widespread effects.

(give at least two reasons.) 3. what is the most important greenhouse gas in the troposphere? 4. what is global warming? how is it different from the greenhouse effect? 5. what is the cause of the increase in the mean global temperature?
When gases in Earth's atmosphere capture the heat from the Sun, the process is known as the greenhouse effect. Earth becomes significantly warmer as a result of this process than it would be otherwise. One of the factors that makes Earth a nice place to live is the greenhouse effect.
More heat from the Sun is being trapped in our atmosphere thanks to the accumulation of CO2 that is released during the burning of fossil fuels. Human-made actions are referred to as anthropogenic actions, and the release of CO2 is one such anthropogenic action that contributes to the current enhanced greenhouse effect.
Global warming is the gradual warming of the Earth's surface that has been seen since the pre-industrial era (between 1850 and 1900), and is attributed to human activity, particularly the burning of fossil fuels, which raises the levels of heat-trapping greenhouse gases in the atmosphere.
